ILLUSTRATIONS OF SOME AFRICAN SPECIES 
buff, and with blue and black colours. The markings of the elytra 
may be traced to those of L. ornata and its immediate allies, the 
second fascia being more attenuated and interrupted than usual, 
and the intermediate patches rather smaller than ordinary. It 
was brought from Pauz Oasis by M. Cailleaux. 
The insect represented in Plate 86, fig. 2, from the collection of 
the late A. H. Haworth, Esq., appears to me to be another fine 
variety of L. ornata, having the thorax and markings on the 
elytra very pale buff; and the sides of the former, behind the 
lateral spines, and the ground colour of the latter, of a bluish- 
green colour; the dark stripes separating the fascim at the base 
of the elytra being much reduced in breadth. Tlie specimen is a 
male, having the mandibles dentated at the base, as in the other 
allied insects. 
It appears also probable that the Cerambyx marmoratus of Voet 
Coleopt. Ed. Panz. 3, p. 21, 20, pi. 7, fig. 20 (Lamia venditaria. 
Sell. Syn. Ins. I, pt. 3, p. 373), the locality of which was unknown, 
is another variety of L. ornata. It is represented as of a fulvous 
colour; the thorax banded with black, and varied with greenish 
at the sides, behind the lateral spines, and with the elytra varied 
with numerous irregular black markings.

This highly beautiful insect is most probably but one of the 
varieties of the type of the genus which is distinguished by the 
angulated shoulders of the elytra, all of which (including several 
of the following insects) will ultimately, in all probability, be 
determined to constitute one extremely variable species, the local 
varieties of which preserve an uniformity in the distribution of 
their colours. Thus, L. chrysopras, from Aquapim, has the 
general colour dark fulvous, with a single green patch on the 
elytra, and the other dark markings almost obliterated; L. 
ornata, in like manner, has but very little green colour visible; 
whilst L. mirabilis is entirely green and black. The chief charac¬ 
teristic of all these varieties seems to be the three spots on the 
middle of each elytron, arranged somewhat in a triangle; and
